PASTE INCLUDING PHOTOCONDUCTIVE MATERIAL, METHOD OF PREPARING PHOTOCONDUCTIVE LAYER, PHOTOCONDUCTIVE LAYER AND RADIATION DETECTOR INCLUDING THE PHOTOCONDUCTIVE LAYER

摘要

PURPOSE: A paste is provides a radiation detector with excellent performance and a photoelectric conversion layer with excellent sensitivity and low dark current characteristics. CONSTITUTION: A paste includes a photoelectric conducting material (10); a binder which has a polymerization degree of 600-1100; and a solvent (30) dissolving the binder. The photoconductive material includes at least one selected from HgI2, PbI2, PbO, TlBr, CdTe, CdZnTe, CdS, and BiI3. The content of the binder is 1-50 parts by weight based on 100.0 parts by weight of the photoconductive material. A manufacturing method of the photoelectric conversion layer comprises a step of spreading the paste on a substrate; and a step of obtaining the photoelectric conversion layer by heat-treating the paste.
